Abu Dhabi's Aabar Investments PJSC reportedly wants to raise its stake in Daimler to 15 percent from 9.1 percent, according to remarks made by the fund's chairman.

Daimler and Aabar yesterday announced the purchase of 75.1 percent of the Brawn Grand Prix racing team, whose driver Jenson Button won this year's Formula One championship.

Since buying the Daimler stake earlier this year, Aabar has teamed up with Daimler on Tesla Motors Inc., buying part of Daimler's 10 percent stake in the electric car company in July.

Aabar Chairman Khadem al Qubaisi told Bloomberg yesterday that the Abu Dhabi-listed investment company was 'in talks' to raise its holding to 15 percent. The timing would depend on the stock price, he said.
